Lotan

Lotan seems to have been prefigured by Têmtum, the serpent killed by the benevolent storm godHadad in Syrian seals of the 18th–16th century BC.

In the Baal Cycle discovered in the ruins of Ugarit, Lotan is a servant of the sea godYammu and is defeated by the benevolent storm godBaʿal, possibly with the help or by the hand of his sister ʿAnat. Lotan or Litanu was his proper name. The account has gaps, making it unclear whether some phrases describe him or other monsters at Yammu's disposal. Most scholars agree on describing him as "the fugitive serpent" (bṯn brḥ) but he may or may not be "the wriggling serpent" (bṯn ʿqltn) or "the mighty one with seven heads" (šlyṭ d.šbʿt rašm).
